Description
Technical field
The present invention relates to electrical cabinet apparatus field more particularly to a kind of fire prevention electrical cabinets.
Background technology
Electrical cabinet is for being arranged the components such as electrical equipment, element.Component in electrical cabinet often generates heat at work, leads
In-cabinet temperature is caused to increase, it is unattended especially in the arduous distributed environments of condition, it is particularly easy to occur that temperature is excessively high has caused
Fire.It is such risk bigger in hot weather on especially.
Accordingly, it is desirable to provide a kind of can also prevent electrical cabinet on fire in unattended arduous distributed environments.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of fire prevention electrical cabinet.
The present invention is achieved through the following technical solutions：
A kind of fire prevention electrical cabinet, including cabinet, further include the moisture-proof bottom plate being horizontally mounted on the ground, and cabinet is vertically-mounted
On moisture-proof bottom plate, moisture-proof bottom plate is used to be isolated the influence of the cabinet of ground wet environment；Several dissipate is offered on cabinet side wall
Hot hole, heat emission hole are in communication with the outside, and provide the channel that heat in cabinet distributes, it is close that heat emission hole upper end is hinged with the energy opened outward
The baffle of heat emission hole is sealed, baffle is opened obliquely, can also prevent rainwater etc. from entering in cabinet in this way；
It is also equipped with installs case connected to the cabinet body on moisture-proof bottom plate, piston cylinder, piston cylinder are horizontally installed in installs case
It is provided with continuous through-hole between cabinet, the piston that can be slidably reciprocated wherein is installed in piston cylinder, wherein in continuous through-hole
It is provided with elastic valve plate, offers stomata on valve block, when original state, stomata is closed；
